One note, your second claim is not entirely true - while land vehicles are a ways from being feasible to power with photovoltaics (although I would have to do the math for trains, which may be close), we already have primarily [1] and exclusively [2] solar-powered aircraft.
Those aircraft limp along at a tenth the speed of a typical commercial flight. That's the main reason I said "effectively". I mean, there are useless pure-solar cars too.
Trains might be closer but when single locomotives are measured in megawatts I'm not very confident.
Going with a weight of 20 lbs/m^2, that's only 600 lbs - less than 1% of the fully-loaded weight.
It's fairly likely one could get well below that mass using some of the more experimental solar panel designs (such as those in use for solar aircraft), but it would probably not be cost-efficient .
Thank you, exactly. I'd rather just pick it up one time and expect that they do it sometimes as well. I don't want it to seem like I actually give a fuck about 12 dollars for the experience of hanging out and having a good time. And I don't.
I refuse to link my financial activity and things involving my physical address to Facebook, which Venmo seems to require. This is insanity to me. And I am a millennial as well.
This is an incredible oversimplification(at best) which does not hold as-is.
I know enough math people who are ABYSMAL at coding due to the differences between domains and the constraints that shaped their way of thinking, and a lot of linguists who are surprisingly good at it due to just that.
Italian major CS minor here:
Not good at math (working on it) but good at programming (full time salaried job with good pay doesn't mean I'm good at it but it'd about the only credential I have) (also working on it).
I dismissed programming as a freshman because I was so bad at math in high school. Turns out my high school teachers were very bad teachers (shocking when they're paid so little, who would've thought? ) I learned Italian fluently, spent a few years overseas immersing myself in it, came home and had a rough time finding my passion. Took a gap year and messed about with some online coding classes (code academy) and realized I loved it. It felt like a new language that instead of being expressively emotional it was a way to express logic and rules. I like logic and rules.
So I completed the minor +4 higher level classes and taught myself mobile development. No regrets... Besides not going into it as a major maybe.
Most of the North Korean people are starving most of the time - where are they practicing programming on, blackboards? The economic situation is VERY similar to Cuba before US lifted the embargo. Has any one of you heard famous hacking group originated from Cuba?
It doesn't directly, but it indicates that the nation has an ability to create a pipeline to identify and train talented students for a high-performance intellectual pursuit if they wish to.
I wouldn't call "not working" "leisure". I work 80+ hours a week myself. But I recognize that there are more important things in this world and in this life than just working.
It's immoral to drive at any speed which causes needless risk of physical harm to other people, speeding or otherwise. There are times when speeding does not cause this risk though.
The phrase "speed excessively" in your second sentence directly implies that "speeding" leads to the immorality rather than just speed. Additionally, "excessive" is approaching a tautology. In your first comment though you just talk about "speeding" without the excess and then say that's flatly immoral.
Sure, but in my experience people who are speeding at 10-20 mph on 35-mph-limited mixed-user surface streets are doing both. That's true as well on rural highways with hidden curves and possibly animals or tractors, or complex urban interstates with lots of traffic merging. These account for a majority of the driving people do. The case of a rural interstate with few interchanges is what people mostly think of with speed limits, but many of these have already been raised to a limit of 70–80 mph.
People are bad at assessing risk and bad at awareness of road conditions. And I think learning to disregard posted speed limits corrodes regard for other rules of the road, like stopping at traffic lights.
>It's immoral to speed excessively in way that causes needless risk of physical harm to other people.
Even in jurisdictions that didn't have speeding laws (before we had a national standard) those people were still prosecuted for reckless driving. The standard speeding law is whatever is reasonable and prudent given the traffic, weather, and road conditions. It's a subjective standard that offers police a lot of leeway, but so it goes.
Normal traffic is driving up to the legal speed limit.
> On the other hand, a New York judge announced that he would not convict drivers for blocking speeding traffic, People v. Ilieveski, 175 Misc. 2d 943; 670 N.Y.S.2d 1004 (Monroe County N.Y. 1998).
Failing to keep pace with the flow of traffic is just as much of a safety hazard. I see near misses all the time on the highway due to people make desperate lane changes to avoid getting stuck behind a slower car.
Mostly I'm talking about surface roads, especially where people go at ~50 mph in a 35 mph zone, without regard for road conditions or other road users.
But drivers have developed a sense of entitlement to speed at least 10 mph, and regard the posted speed limit as a speed minimum. But if a car is traveling 65 mph in a 65 mph zone in a center or right lane, and a car behind him traveling at 75 mph swerves recklessly into another lane in order to avoid having to slow down to the posted speed limint, then the responsibility for the risk of that unsafe lane change is the responsibility of the driver who did it, not the car driving at the posted speed limit in the right lane.
The National Maximum Speed Limit law was passed in 1974 and repealed in 1995. It's been repealed for longer than it was in effect. Virtually all of the lower 48 US states have an interstate speed limit on the order of 70-80 mph.
Yes, though a lot of them have 85th percentile speeds more than 5 mph above the speed limit. And they still have a tendency to randomly reduce the speed limit to 55 mph without any obvious difference in road design (Pennsylvania and Maryland for example). Also, a lot of those states only recently allowed speed limits above 65 mph (far more recently than 1995).
So you basically have a generation of motorists who grew up and spent a substantial portion of their driving years with highway speed limits that virtually no one complies with, and that it was okay to drive 5 to 10 mph above the speed limit. This attitude spread to other road types as well meaning that even appropriately posted speed limits (e.g., 25 mph residential streets) have a high degree of noncompliance.
It's going to take a while to undo the damage, but that's what happens when traffic control devices are effectively used to "cry wolf".
The key word there is "excessively". Going faster than the posted speed limit doesn't mean you're endangering others. And, heck, driving at or lower than the posted speed limit also doesn't mean that you aren't endangering others (e.g. under poor weather conditions).
Fucking obviously they are too low. Everyone knows this. Absolutely no one drives exactly the speed limit. Speed limits are low to increase revenues from speeding tickets.
